Bar plot color, why [1 0 0] does not gives red

Hi All and thanks for reading this.
I want to color some of the bars in this plot in red but the color I get is not as expected (as for rgb = [1 0 0] )
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1066605/image.png)
Am I doing something wrong? or ....
My code is below
figure('Color','w', 'Units','normalized', 'Position',[0.3906 0.6778 0.2037 0.2514])
yDataGreen = [ 5 7 9];
yDataRed = [ 6 8 10];
xData = 1:3;
barPlot1 = bar(xData, [yDataGreen; yDataRed]) ; hold on; grid minor; box on; title('That does not look the Red I want')
barPlot1(1).FaceColor = 'flat';
barPlot1(1).CData(:,:) = [0 1 0; 0 1 0; 0 1 0]; %green
barPlot1(2).CData(:,:) = [1 0 0; 1 0 0; 1 0 0]; %red

You have to set FaceColor to 'flat' in order for CData to take effect, which you are doing for the first bar but not for the second.
figure('Color','w', 'Units','normalized', 'Position',[0.3906 0.6778 0.2037 0.2514])
yDataGreen = [ 5 7 9];
yDataRed = [ 6 8 10];
xData = 1:3;
barPlot1 = bar(xData, [yDataGreen; yDataRed]) ; hold on; grid minor; box on; title('Now that does look like the Red you want')
barPlot1(1).FaceColor = 'flat';
barPlot1(2).FaceColor = 'flat'; % set both
% or set both at once:
% set(barPlot1,'FaceColor','flat')
barPlot1(1).CData(:,:) = [0 1 0; 0 1 0; 0 1 0]; %green
barPlot1(2).CData(:,:) = [1 0 0; 1 0 0; 1 0 0]; %red
